This sort of deliberate mischaracterisation has no value in discussion. Republicans have definitely ridden high on stopping the suffering - perceived or otherwise - caused by objective, Democrat-led encouraging of illegal immigration across the southern border of the US. And even they wouldn't be as bad faith as you and claim that Democrats wanted that suffering.
The idea that Democrats want a freely open southern border is just as false as Republicans are the party of fiscal responsibility.

Tell me as what else than deliberate want for suffering I should perceive the actions of ICE? There are rules and processes to deport people that are deliberately being broken by masked thugs not identifying themselves.
A discussion about enforcement of rules or even if these rules make sense (with the conclusion, say, of handing everyone who has legally worked and stayed out of trouble for anything but traffic tickets and smoking pot a permanent residence) might be had, I don't deny that. But the way the current administration runs rampant? That doesn't answer any of the multitude of questions, it just makes life hell for everyone affected - children that are US citizens who come home only to find out their parents got snatched by an ICE raid on their workplace, people who get deported to CECOT or other hellholes with no due process at all on sometimes not even evidence but outright fabrications, employers who have half their work force either snatched up and deported over night or the work force just vanishing because they are afraid of ICE even though they have legal status...
Oh and even before that, 'member Covid? People trying to apply for unemployment benefits who got stuck in bureaucracy?
With the current Republicans I am far beyond giving them the usual excuse of "don't assume malice when stupidity is sufficient".
